| 2008年11月至2009年10月对分水江水库鱼类资源进行了调查， 共调查8船次，统计渔获物142.48kg,测量鱼类标本1304尾，经鉴定共发现鱼类36种，隶属5目8科31属，其中鲤形目26种，占总种类数的72.2%；鲈形目和鲶形目各4种，分别占总种类数的11.1%；鳗鲡目和合鳃目各1种，分别占总数的2.8%。群落优势度分析发现，优势种有5种，优势度变化范围为0.38~0.61。多样性指数分析表明，鱼类种群丰富度指数（D）值在1.14～5.42之间，Shannon-Wiener 多样度指数（H′）值在 0.69~2.60之间，种类均匀度指数（J′）值在0.31 ~1.21之间。鱼类群落的季节差异性较高，种类变化波动以夏季最大。 |

| The fish resources investigation in Fenshuijiang reservoir was carried out from November 2008 to October 2009. 142.48kg fish capture was obtained by 8 sailings and 1304 fish specimen were measured. There were 36 species of fishes, which belonged to 5 orders 8 families 31genera. Cyprinidae was the largest order, which accounted for 72.2% of the total. Siluriformes and Perciformes accounted for 11.1% of the total identically. Anguilliformes and Synbranchiformes accounted for 2.8% of the total identically. It was indicated that there were 5 dominant fishes by analyzing the dominance of fish communities，and the dominance varied from 0.38 to 0.61.Three diversity indexes which were species richness index (D)，Shannon-Wiener index (H′) and species evenness index(J′)were used to analyze the diversity characteristics of the fish communities. The value of D, H′ and J′ varied between 1.14～5.42, 0.69～2.60 and0.31～1.31 respectively. It was indicated that difference of fish communities in different seasons was high. The magnitude of changes was most obvious in summer. |
